Abstract
Methods of forming an electrically-conductive mesoporous carbon structure with interconnected pores or highly interconnected pores, and the resulting structures are described. The structure is formed by providing a mesoporous template, filling the mesopores with an organic precursor, polymerizing the organic precursor, pyrolyzing the polymerized organic precursor, and etching away the template.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A film with a porous carbon structure, comprising:
an electrically-conductive porous carbon structure with interconnected pores;
wherein said carbon structure is formed in a mesoporous template film with cubic mesostructural ordering having a plurality of mesopores by filling the pores with an organic precursor, polymerizing the organic precursor, pyrolyzing the polymerized organic precursor to produce electrically-conductive carbon, selectively removing the template film to yield said electrically-conductive porous carbon structure with interconnected pores; and
wherein at least 50% of the pores are interconnected to at least one other pore within the carbon structure.
2. A film as recited in claim 1 , wherein said mesoporous template film comprises a material selected from the group consisting of silica, titania, alumina, oxides, organosiloxanes, nitrides, phosphides, carbides, chalcogenides, organometallic compounds, metals, or mixtures thereof.
3. A film as recited in claim 1 , wherein said organic precursor is selected from the group consisting of sucrose, phenolic resin, resorcinol, naphthalene, furfuryl alcohol, or aromatic-containing organic precursors.
4. A film as recited in claim 1 , wherein said porous template film comprises a mesoporous film with body-centered-cubic Im 3 m ordering.
5. A film as recited in claim 1 , wherein said porous template film is prepared by spin-coating, dip-coating, or casting a structure-directing organic species in the presence of a network-forming inorganic species, followed by removal of said structure-directing organic species.
6. A film as recited in claim 1 , wherein said electrically-conductive mesoporous structure comprises a mesoporous film.
7. A film as recited in claim 1 , wherein said porous carbon structure has a surface area greater than approximately 100 m 2 /g.
8. A film as recited in claim 1 , wherein said porous carbon structure has an electrical conductivity greater than approximately 5 S/cm.
9. A film as recited in claim 1 , wherein said interconnected pores are highly interconnected with greater than 90% of the pores interconnected to at least one other pore.Cited by (0)
